Softupdates give you an "insurance" that, in the event of a crash or a=20= power outage, your filesystem will be coherent enough to be recoverable=20= by fsck. This is the same goal as journalisation, just a different=20 method. However, any data not fully commited to disk is forever lost. I guess=20 this applies to unsaved documents. Note that the hard disk's write cache should be __disabled__ or there's=20= no point in using softupdates at all. Up to now, there's no support for=20= "safe write cache" operation. To my knowledge, it only exists in=20 windows 2000 sp3 and xp. (it has been found ... inoperant in w2k <sp3!). hope this helps Raphael Le mercredi, 16 avr 2003, =E0 22:02 Europe/Zurich, David a =E9crit : > I have freebsd 5.0 and it uses softupdates which I hear > it is better or equal to journal filesystem.
